Summary -Cryptophanes are hollow molecules of nanometric size made of two cyclotriveratrylene units assembled in front of one another by three spacer bridges. In this paper, we focus on the synthesis and characterization of medium and large cryptophanes h

Dihalides X-(Z)-X, [Z = (CH2)n; n = 1-7 or CH 2CH=CHCH2] react with the phenol group of vanillyl alcohol to give the dialkylated derivatives HOCH2-Ar-O-(Z)-O-Ar-CH 2OH (2), which in turn, in the presence of formic acid, afford the corresponding D3 cryptophanes (3), with, in some cases, minor amounts of the C3h isomers (4).
